lastmonth
Resolve "lastMonth" to a concrete ISO date range relative to your run time — the previous full calendar month. Returns inclusive civil dates plus exact UTC instants so you have temporal context without computing dates by hand. Read-only: no writes, no network. Use before a task over last month (monthly reports, month-end summaries).

## /lastMonth
Get the concrete date range for **the previous full calendar month** by running the bundled resolver:
```bash
node "$AGENT_DIR/.claude/skills/temporal/when.mjs" lastMonth
```
It prints a human-readable line plus a JSON record:
- `start` / `end` — inclusive civil dates (`YYYY-MM-DD`) in your local timezone
- `startUtc` / `endExclusiveUtc` — the same window as a half-open `[start, end)`
range of exact UTC instants, for timestamp-based queries
- `days`, `timezone`, `asOf` — the span, your timezone, and when this resolved
Use the returned dates as the time bounds for the task at hand. **Do not derive
dates by hand** — this resolver is the source of truth. For the full window list
or an arbitrary range (e.g. `last45days`, `last6months`), see the `/temporal` skill.
